Abstract
An in-house blind trial on Norway lobster (Nephrops norvegicus) was ca rried out in which 72 coded samples were correctly identified. The sam ples were either left unirradiated or had been given doses of 1.03, 2. 39 or 3.40 kGy and stored for 0, 7 or 14 days at 1 degrees C. Using re -irradiation, the doses received by the samples identified as irradiat ed were determined with either linear, quadratic or asymptotic equatio ns being fitted to the data. The most successful estimates of absorbed dose were obtained using a quadratic fit, with average values of 1.71 , 2.98 and 3.45 kGy being calculated.
